Table 1.

Night CSF sample group: means ± standard deviations and statistical comparisons between groups. * indicates significant difference (p<0.05) from control and ** indicate significant difference between High and normal 3OMD. ANOVA is used for the comparison for all groups with pair-wise comparisons using FPLSD. The PLMS/hr and JHRLSS are only compared between normal and high 3OMD using t test.
